Ladders are utilized in various capacities for common maintenance upon buildings as well as in emergency situations for ascending upon structures or providing alternative escape routes therefrom.
Ladders are a common means for providing access to upper regions of various structures and of course are well-known in the art. In emergency-type situations, such as use by fire and police, ladders are utilized for ascending structures in often adverse circumstances.
In the case of a fire in a building or other structure, it is normal practice within the discipline of firefighting to provide alternative escape routes from buildings. One form of an alternative escape route is to provide a ladder at a perimeter region of a building. During a fire smoke is emitted, and due to the continually fluid nature of unpredictable events the environment may be very stressful and chaotic. Oftentimes the adverse circumstances can impede the senses when determining the location of a ladder. Whether the ladder is utilized as a primary means of embarking upon the building or as a backup exit strategy, knowledge of the location of the ladder is imperative.
Over the years the fire service has increased safety standards substantially and is continuing to come up with new ideas to help keep firefighters healthy. Often firefighters must carry out their duties in the midst of darkness and visibility is often low due to smoke conditions. In any structure fire situation, there are multiple ladders either going to the roof so crews can perform ladder company operations, or ladders extend to exterior windows so crews inside have emergency egress routes.
Oftentimes firefighters ascending to the roof will put a ladder up to gain access and begin performing their assigned duties while relying on other personnel to set up secondary means of egress. This is very time efficient, but unfortunately crews can become disoriented under smoky conditions and may not be able to visualize egress routes due to certain fire situations.
Engine and ladder companies may be inside the structure fighting fire and performing search and rescue operations while ventilation is being performed on the roof. These crews must also be aware of their egress routes for victim removal and emergency exit. Often heavy dark smoke will not allow crews to see the exterior windows where ladders have been placed for them, and at times radio traffic can be unclear when relaying commands to interior crews.
In such a circumstance where smoke emission is excessive, it is most desirable to locate the ladder by way of visual cues.
Therefore, providing a ladder with an illuminating beacon or otherwise illuminating portion to aid in the location of the ladder can be of great use in emergency situations as well as other circumstances. In other forms, the illuminating portion of the ladder cap can provide functional illumination of a surrounding such that in one form, an illuminating region is projecting a light to illuminate immediate surroundings upon the end portion of the ladder.
